The 6 Best Tub Repair Kits of 2025

Best Overall

Bathworks Tub and Tile Chip Repair Kit

$38 at Amazon $38 at Home Depot $38 at Lowes

Bathworks offers a whole line of DIY kits for complete tub refinishing, but we like the brand's Chip Repair Kit as a versatile solution for minor damage on tubs and a variety of other bathroom surfaces, such as sinks. The 4-ounce compound can repair approximately a dozen small scratches or chips the size of a quarter. 

As with most resin-based filler compounds, you'll start by mixing together two separate ingredients: three parts of the primary filler and one part of the cream hardener. The mixture will harden within two minutes, so use what you've mixed to fill the damaged spot, let it dry (aided by a hair dryer if you're impatient), then sand it down with the included 120-grit sandpaper. 

To finish the surface (assuming you're not doing a separate refinish of the entire area), the kit includes a bottle of waterproof repair paint and a small paintbrush to apply it with. Even with a small repair, you'll still need to wait a day for your work to fully cure and dry before you use it. 

One thing to keep in mind is that the color may be slightly off, which is often a challenge for surface repair products to get precisely right. The Bathworks chip kit is available in six common color options so you can match your existing fixtures as closely as possible, but it doesn't include color mixing ingredients to adjust the hues.

Best Budget

Keeney Tub Repair Kit

$20 at Amazon $46 at Lowes View on Menards.com

Kits for smaller tub repairs are generally not very costly, and we think the Gel-Coat Products Tub and Shower Repair Kit offers solid bang for your buck. You can find it in three different colors (white, bone, and biscuit) for $20 or less, though some stores may have certain colors at higher prices, depending on availability. 

Like our overall best pick, the Bathworks Chip Repair Kit, this package supplies all the basic tools you'll need to fix up cracks and chips. There's the main gel-coat putty, a liquid hardener, and a stick for mixing and application. It also includes alcohol wipes for cleaning and two different grits of sandpaper after it's dry, which can take a pretty quick one to three hours. 

Note that there's not an actual finish to apply at the end; there is only a polishing compound to wipe onto the area. If you happen to be refinishing your bathtub but have a few holes or chips to fill first, this kit can be a good addition to the project, especially since it doesn't add that much to the total cost of refinishing your tub. You get enough material to cover about 18 square inches—and it works for patching up fiberglass on boats, too.

Best for Refinishing

Ekopel Roll On Bathtub Refinishing Kit

View on Amazon View on Walmart

For tubs with significant discoloration, deterioration, or overall disrepair that you wish to freshen up on your own, the Ekopel Roll On kit can help make it happen. The original pour-on version of Ekopel 2K was a staple of serious home refinishing, but this newer mixture is designed for roll-on application and is much more user-friendly. You do need to provide your own rollers, paint trays, and other necessary equipment, and be aware that foam or nap rollers have the risk of leaving behind bubbles or fibers in your coating. 

The kit provides plenty of material for two coats on one tub; bigger bundles are available to cover surrounding tiles as well. Mix parts A and B of the Ekopel 2K to apply the first coat, wait three to five hours until it's dry, then do the same with the second pair of compounds. You might notice some odor from the mixture, but less so than most other products. The tub should be ready to use after 24 hours, but it's recommended to wait a few weeks for a complete cure before using hair coloring or any colored products that may stain the finish. 

In general, the results of tub work depend heavily on how thoroughly you've prepped and cleaned your surfaces, and that's especially true when refinishing with Ekopel. This process can include scrubbing, sanding, careful application, and covering your drain or potentially removing it.

Best Spray

Rust-Oleum Specialty Tub and Tile Spray Paint

$30 $13 at Amazon $13 at Walmart $19 at Home Depot

A spray-based epoxy, like Rust-Oleum's Tub and Tile Aerosol, is the way to go if you're looking for a smooth, simple process of applying a new finish to your tub. Stray marks, fibers, and other imperfections that brushes or rollers may leave behind aren't nearly as much of a concern when you're simply passing over the surface with a spray can. The fumes are strong, though, so remember to wear a mask and keep your space well-ventilated. 

The 12-ounce canister, available in a white or a grayer "coastal fog" color, can treat about 15 square feet of surface area on a tub, sink, or tile floor. You can use it to refinish an entire bathtub, but be prepared to buy multiple cans for full coverage. A single layer of the finish also won't be as thick as its paint-on counterparts, so you may need to apply two or more coatings to get the protection you need. 

The spray dries quickly, in about 15 minutes, but you'll need to leave the surface unused for a pretty lengthy 72 hours to fully cure. With sufficient prep work and application, it should leave your stained or scuffed area looking much improved, with less hassle than many other repair and refinishing options.

Best for Color Matching

Fortivo Tub and Tile Repair Kit

$19 $16 at Amazon View on Fortivoshop.com

The Fortivo Tub and Tile Repair Kit aims to help with one of the trickier aspects of crack or chip repair jobs: matching the exact color of your tub. This isn’t an issue if you're completely coating your tub with a new finish of one particular color, but if you're only filling in a small area, you want it to blend in with the surfaces all around it.

With the multicolor Fortivo kit (a plain white version is also available), you get five small cups containing white, black, cream, tan, and red paints. In the included mixing bowl, you mix equal amounts of part A and part B of the main filler compound, along with tiny quantities of the colors you need, based on the tint of your tub or sink (we recommend gradually adding color, one toothpick drop at a time). There's no guarantee you'll be able to create an exact match, but it should blend better than a single preset color, for no significant added cost. 

As a repair product, the Fortivo kit is similar to our best value pick, the Gel-Coat Products Tub and Shower Repair Kit, in that it's meant to address smaller chips and dents, and doesn't come with a finishing compound for after you've filled in the damage. Fortivo's compound takes longer to dry, though, with an estimated 24 hours of time to cure on average.

Best for Large Repairs

Tub Repair Company Floor Crack Repair Kit

$170 at Amazon

If you're looking to salvage a tub or shower with significant cracking on the floor, your best bet is a specialized set of materials like the Tub Repair Company's Floor Crack Repair Kit. When there's damage to an area of the tub you stand on, a typical patch-up won't be enough to prevent the crack from flexing under your weight and letting water in. The Floor Crack Repair Kit, as the company's "level 3" product for the most critical damage, includes expanding foam that provides support below the crack so it can hold up for long-term use. 

For the rest of the repair process, you get glass putty for filling the crack, finish putty, and finishing paint with a variety of colors to blend in for color matching. Also in the package are basic tools ranging from gloves to spreaders and stirrers, as well as five types of sandpaper. Other pieces of equipment recommended to aid with the process include a power drill for injecting the support foam, an orbital sander, and a respirator for the fumes. 

It's a larger investment in materials, as well as in your effort and time, with drying required in between steps, plus a final 24 hours to fully cure. If done right, though, your work can save you from the much higher costs of replacing your tub. If you need more assistance, the company offers instructional videos on their website along with phone support to help guide you through the process.
